Picking a TypeScript OSS E-Commerce Platform in 2026 — Medusa v2, Vendure v3, and Where EverShop Fits

After several years of headless and composable consolidation, the realistic shortlist for TypeScript-native OSS e-commerce platforms in 2026 has collapsed to Medusa v2 and Vendure v3, with EverShop as a lightweight integrated alternative. Saleor (Python core) and Next.js Commerce (storefront framework without an EC API) sit outside the TypeScript-native scope used here; Reaction Commerce is discontinued. This post compares the three on license, architecture, and AI / Agentic Commerce readiness, then maps the choices to use cases.
